SN74LVTH574PWR

Texas Instruments · Flip Flops · TSSOP-20

SN74LVTH574PWR from Texas Instruments, in a TSSOP-20. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OE input Active-low output enable control; low enables Q outputs to normal logic levels, high places outputs in high-impedance state.
2 1D input Data input for flip-flop 1, captured on CLK rising edge when OE is low.
3 2D input Data input for flip-flop 2, captured on CLK rising edge when OE is low.
4 3D input Data input for flip-flop 3, captured on CLK rising edge when OE is low.
5 4D input Data input for flip-flop 4, captured on CLK rising edge when OE is low.
6 5D input Data input for flip-flop 5, captured on CLK rising edge when OE is low.
7 6D input Data input for flip-flop 6, captured on CLK rising edge when OE is low.
8 7D input Data input for flip-flop 7, captured on CLK rising edge when OE is low.
9 8D input Data input for flip-flop 8, captured on CLK rising edge when OE is low.
10 GND power_in Ground supply reference.
11 CLK input Positive edge-triggered clock; transfers D inputs to Q outputs on rising edge.
12 8Q tri_state Three-state Q output for flip-flop 8; active when OE is low with IOL = 64 mA and IOH = −32 mA.
13 7Q tri_state Three-state Q output for flip-flop 7; active when OE is low with IOL = 64 mA and IOH = −32 mA.
14 6Q tri_state Three-state Q output for flip-flop 6; active when OE is low with IOL = 64 mA and IOH = −32 mA.
15 5Q tri_state Three-state Q output for flip-flop 5; active when OE is low with IOL = 64 mA and IOH = −32 mA.
16 4Q tri_state Three-state Q output for flip-flop 4; active when OE is low with IOL = 64 mA and IOH = −32 mA.
17 3Q tri_state Three-state Q output for flip-flop 3; active when OE is low with IOL = 64 mA and IOH = −32 mA.
18 2Q tri_state Three-state Q output for flip-flop 2; active when OE is low with IOL = 64 mA and IOH = −32 mA.
19 1Q tri_state Three-state Q output for flip-flop 1; active when OE is low with IOL = 64 mA and IOH = −32 mA.
20 VCC power_in Positive supply voltage; operating range 2.7 V to 3.6 V.
